WINDOW-SASH BALANCE.

Application filed November 2, 1921. Serial No. 512,177.

T0 aZZ wh.om it may concem:

Be it known that we, EDGAR L. GARDNER and JAY L. WILLARD, of Bochester, in the countv or Monroe and State of New York, have invented a certain new and uset'ul Improvement in lVindowSash Balances; and we do hereby declare the followmg to be a full, clear, and exact description of the same, reference being had to the accompanymg drawing, forming a part of this specification, and to the reference numerals marked thereon.

Our present invention relates to building construction and, more particularly, to windOW sashes and balances therefor, and it has for its object to provide a simple, cheap and convenient sash and balance construction whereby the sash cord may be readily connected with or disconnected from the sash without removing the latter or any other part, and without the use of tools. To these and other ends the invention consiste in certain improvements and combinations of parts, all as Will be hereinatter more fully described, the novel eatures be1ng po1nted out in the claims at the end ot the specification.

In the draWin s:

Figure 1 is a fragmentary view partly in section ci a window frame and sash provided with a sash balance connected in accordance with and illustrating one embodiment of our invention;

Figure 2 is a vertical sectional view, en-

larged, through a fragment of the sash showing the manner in which the sash cord is inserted and engaged;

Figure 3 is a similar view showing the cord fully engaged;

Figure 4 is a side view of the sash and its cord connections, and

Figure 5 is a detail perspective view of the attachment plate.

Similar reference numerals throughout the several views indicate the same parts.

Ve have illustrated our invention in the present instance in connection with a spring controlled sash balance as distinguished trom the counter weighted type. The window trame with its stop strip 1 is indicated at 2, and is outaway at 3 to receive the casing 4. of the balancing device which has flanges 5 by means et which it is secured to the face et the casing. As is well known these balances comprise a spring drum (mot shown) beyond the hook.

face thereof which slides on the frame at a point near the top is provided with a cavity or recess 10 and with a communicating slot or channel1l thabmay be shallower and that extends to the top edge or corner of the sash. The sash cord 7, normally lying against the face of the frame may be let down into this cavity 10 through the slot- 11, as shown in Figure 2, and it normally occupies the slot, as shown in Figure 1.

In the cavity 10 is located a plate 12 that may conveniently consist of a sheet metal stamping and which is secured to the sasn at the bottom of the cavity by a screw 13 or otherwise. An car 14 struck from the plate and offset forms a downwardly turned hook that may be reintorced by an inclined car 15 struck from the edge of the plate just above it. Below this h-ook Mat a suitable distance a tongue or projection 16 is struck up in a similar manner and disposed angularly as shown in the figures to reach out This projection constitutes an incline or cam surface that blocks the cavity from zibove and serves to direct an object inserted through the slot 11 to ward the side of the cavity and to a point beneath the hook 14.

The ee 8 on the lower end of the sash cord 7 preferably has a suitable connectionwith the latter at 17 and in the operationof the device when it is desired to* attach the sash cord to the sash the cord is lowered into the slot 11 and cavity 10 in the manner shown in full lines in Figure 2. When the e re 8 strikes the cam pro ection 16 it is dereversed and a suitable manipulation et the At its lowercord caused t0 efi'ect its removal Without reengaging the hook.

This attachment and disengagement without the use of tools or the removal of any of the parts is partiou1arly useful when a sasn cord breaks and must be renewed.

We daim as our invention:

1. In a sash balance the oombination with a casing and a sash abutting the same and having a recess in its abutting face, of a dow1nvardly turned hook in the recess, a sash cord depending from the casing and having an eye at its lower and and means on the sash for automatically directing the eye into e1lgaging position with reference to the hook when the sash and cord is lowered between the sash and casing.

2. In a sash balance, the combination with a casing and a sash abutting the same and having a 1ecess in its abutting face, of a d-Ovvnwardly turned hook in the recess, a sash cord depending from the casing and having an eye at its lower end and an inclined projection on the sash Within the recess and below the hook for direotng the eye into engaging position With reference to the hook when the sash cord is lowered between the sash and casing.

3. In a sash balance, the combination with a casing and a sash abutting the saine and having a recess in its abntting face of a plate arranged in said recess and having a downwardly turned projection st1uck therefrom and constituting a hook and an upwardly turned inclined projection struck thereirom below the hook, and a sash nord depending from tHe casing and provided with an eye at ns 1ower end adapted to strike the inciined projection when lowered into the reoess and to be directed thereby into engaging position with reference to the hook.
